Let us suppose, then, that in preparing for the cantering lesson on the curb, in order nicely to collect the horse, the reins are drawn quietly through the left hand by the right, as above described, the object being to rein the horse back a step or two, and balance him well with forehand up and haunches under him. By the above-named drawing up of the reins a firmer _appui_ is created against the horse's mouth. By closing both leg and whip, however, while still maintaining this _appui_, the horse will step back. The instant he does the reins should be yielded to him, and he will bend in the poll of the neck and yield to his rider's hand. So that the _appui_ is then scarcely perceptible. This alternate action of hand and leg, aided by the whip, should be repeated just as many times as it is desired to rein the horse so many steps backward, the latter moving very slowly; a couple or three steps for the purpose above named are always sufficient. To move the horse to the front again at a walk, the leg should be closed, and the reins eased until he moves forward, when he should be again collected. But if the rider desires to strike him off at once at a canter, at the moment she eases her hand she should apply her spur smartly just behind the girth, and touch the horse lightly on the off shoulder with her whip. Being properly bent and prepared, he will then strike off with his right leg first, and well within himself; but having eased the reins as the horse takes his first short stride forward, the rider should feel them again the next instant, keeping her left hand well back, her arm steady, and manipulating the reins with the right hand and the fingers of the left, so that she feels them just as the horse's fore foot is on the ground, and eases them as he raises it. This may appear to the uninitiated a very difficult matter, but in reality it is not at all so, any more than it is difficult in dancing to keep time to music, or for the musician to count the time to himself; and by careful watching it can be mastered as well as either of the above, or the stroke in swimming. Anybody who has witnessed a cavalry field day will have noticed that the regimental band and the action of the horses both in trotting and cantering past the commanding officer are in exact harmony; and many people believe that the horses are taught to canter to the music. The reverse of this, however, is the case. The leader of the band, having himself passed through a course of equitation, knows the exact cadence of the pace of manoeuvre, and regulates the time of the music accordingly; but it is because he is able to count the time of the horses' footfall so well that he is also able to set the time of the music. In like manner the fair equestrian, with a little practice, can learn to count the time of her horse's canter to herself, and regulate the action of her hand accordingly.
